ESP32-C6 image footer
=====================
Checksum: 0xeb (valid)
Validation hash: ead439409b0196190e8f14987102d104bfc347726069a2115f32456b09de3895 (valid)
0xabcd5432

What is the Expected Behaviour?

Application information to be the last section of the report.

More Information

The tool is looking for DROM segment for application information, when the image header resides in the first IROM segment in the ESP32-C6 image.

Other Steps to Reproduce

Hi @mzakharocsc, thanks for noticing this. You are not entirely right, because DROM and IROM segments share the same address space for newer chips, so the data are still in DROM, only the address is incorrect. Will fix that as soon as possible.
